6.2.1
X3: USB 2.0 DualRole (Type C)
The USB Type-C interface serves as the online interface between the device and the pro-
gramming software.
It should be noted that many of the USB devices on the market do not comply
with USB specifications; this can lead to device malfunctions. It is also possi-
ble that these devices will not be detected at the USB port or function cor-
rectly. It is therefore recommended that every USB stick or USB supply be
tested before actual use.
6.2.2
X4: microSD Card
It is recommended that only storage media provided by SIGMATEK be used.
For the appropriate storage media, see chapter 14.1 microSD Card.
The number of read and write actions have a significant influence on the
lifespan of the storage media.
The microSD card is not intended as an exchangeable medium and should
therefore be removed from the card holder for maintenance purposes only.
